Police commander Blake Chou told several media outlets that three bicycle officers were patrolling the area near Sixth and Union streets Sunday afternoon when a pedestrian flagged them down and said a man was threatening people with a knife.

Chou says the officers quickly found the man, ordered him to drop the knife, and shot and killed him when he would not.

The man’s name and age were not immediately available.

No one else was injured.

It was reported that some residents yelled at police, calling them killers, and said the man they shot was a vagrant but not dangerous.
